Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147485754, here are decompositions:

67 + 2147485687 = 2147485754
163 + 2147485591 = 2147485754
181 + 2147485573 = 2147485754
307 + 2147485447 = 2147485754
331 + 2147485423 = 2147485754
373 + 2147485381 = 2147485754
397 + 2147485357 = 2147485754
487 + 2147485267 = 2147485754

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.0.8.58.
